Dual Leaflet Heart Valve Prostheses in Pyrocarbon for Enhanced Performance

The uniqueness of monolithic pyrolytic carbon technology provides significant advantages in durability and reliability. The free rotation of the flaps around the central axis increases the thromboresistance of the prosthesis. The special design feature ensures improved washing of the hinge assembly by the regurgitant blood flow.

Immunisation of sodium heparin and antibiotics into the cuff provides reduction of bacterial endocarditis and thrombosis in the early postoperative period. Introduction of silver thread into the cuff provides protection of the prosthesis against late bacterial endocarditis. High reliability of the prosthesis is achieved by manufacturing the body and flaps from pyrolytic carbon, which has unique biocompatibility and excellent wear resistance.

Modifications: aortic disc mechanical valve, mitral disc mechanical valve.
